Sifting through matchups can go a long way toward defining fantasy football success, especially in leagues with more than 10 teams. And when bye weeks and injuries enter the equation, the waiver wire becomes a bigger and bigger part of building lineups.

We'll take a look at 10 commodities who can fill in when emergencies strike. These are players available in at least 40 percent of standard leagues, including popular free agent targets Julian Edelman, Brian Hartline and Jordan Cameron.

1. Josh Freeman, QB, Tampa Bay Buccaneers: A 15-for-31 effort in Week 1 has Freeman on the outside of fantasy lineups looking in. He's erratic and mistake-prone, but can also catch lightning in a bottle. He has a good track record against the Saints, whom he faces in Week 2, with 699 yards, 3 TDs and 4 INTs in two meetings last season. Those who own Tony Romo or Matt Schaub might want to consider Freeman instead.

2. Philip Rivers, QB, San Diego Chargers: Rivers wasn't perfect in his season debut, completing 14 of 29 passes for 195 yards in a Week 1 loss to the Houston Texans. But Phillips managed four touchdown passes without unleashing star tight end Antonio Gates. Rivers faces an Eagles defense that overperformed against Washington and is most vulnerable in the secondary. Rivers could have a big day as a "super sub."

3. Da'Rel Scott, RB, New York Giants: David Wilson has the public confidence of coach Tom Coughlin after losing two fumbles against Dallas last week. Heading into Week 2, one has to wonder if he'll land in Coughlin's doghouse again with another untimely miscue or if he'll be overly cautious of making mistakes. Scott would be the beneficiary in either scenario.

4. Bilal Powell, RB, New York Jets: Powell is still available in plenty of leagues after rushing for just 29 yards in Week 1. It's worth noting that Tampa Bay led the NFL in run defense last season and Powell did get involved in the passing game with 4 catches for 35 yards. That trend should continue with rookie Geno Smith under center, giving Powell emergency FLEX potential in PPR leagues.

5. Brian Hartline, WR, Miami Dolphins: Hartline followed his first 1,000-yard season with 9 catches (on 15 targets) for 114 yards and a touchdown in a Week 1 victory over Cleveland. The dynamic could change as deep threat Mike Wallace gets more involved in the offense, but there's plenty of reason to believe Hartline makes weekly contributions on his way to another 1,000 yards.

6. Julian Edelman, WR, New England Patriots: With the Patriots scrambling for known commodities in the passing game, Edelman rose to the occasion with 79 yards and 2 TDs last week. Danny Amendola is doubtful with a groin injury, making Edelman the de facto top target for QB Tom Brady. Edelman has long-term potential but is a must-start as a WR2 or WR3 this week.

7. Doug Baldwin, WR, Seattle Seahawks: Baldwin is an intriguing player owned in less than four percent of ESPN.com leagues. He has a good rapport with quarterback Russell Wilson, hauling in seven catches for 91 yards in the Seahawks' Week 1 win. Four of those grabs were in clutch, third-down situations, further endearing Baldwin to Wilson and Pete Carroll. There's PPR potential here, even this week against San Francisco.

8. Jordan Cameron, TE, Cleveland Browns: After taking the fantasy football world by storm in Week 1, Cameron draws another friendly matchup in Week 2. The Ravens defense, for all its might, proved ill-equipped to deal with Julius Thomas in Week 1 with a plethora of new faces at linebacker and safety. Cameron, a similarly athletic former basketball star, should have plenty of success, too.

9. Kellen Winslow, TE, New York Jets: Winslow was targeted frequently by rookie QB Geno Smith in catching seven passes for 79 yards and a touchdown last week. The Jets will keep things simple for Smith, with short looks to tight ends and running backs, putting Winslow in position for future success. Health will be the key, but Winslow (knee) is probable for Week 2 against the Patriots.

10. Oakland Raiders D/ST: This could be a reach in shallow leagues, but in deep leagues with several top units -- San Francisco, Seattle, Denver -- facing difficult matchups, Oakland could be a one-week play at home against Jacksonville. The Jaguars failed to score an offensive touchdown in a 28-2 loss to Kansas City and again named veteran backup Chad Henne their starter again this week.
